Medical students’ only exposure to a dislocated shoulder reduction before performing it themselves is observing an experienced doctor perform one. However, lack of practice of the procedure can lead to severe and painful complications that may require surgical intervention. This pain and financial burden could be avoided with proper practice. Through the integration of biomechanics and electronics, we have developed a device that can accurately simulate an anteriorly dislocated shoulder (i.e. the most common type of shoulder dislocation) and to teach students the Hennepin Technique. Various mechanisms and features are used to mimic the functions of the human arm and upper torso. Force and angular velocity sensors are incorporated as a part of the simulation diagnostics. A display window is also implemented to give the users real time
